Here's an odd pairing for you: Mastodon has teamed up with Canadian singer-songwriter Feist -- who you might remember from those "1, 2, 3, 4" Apple commercials from a few years ago -- to put out an exclusive split seven-inch single. It's all part of that growing new phenomenon, Record Store Day, which takes place April 21.

Jack White's new album, Blunderbuss, will be released April 24, and we've posted previews and videos of two singles, "Sixteen Saltines" and "Love Interruption." But for those of you who wonder what inspires White these days -- let alone what a blunderbuss is -- The New York Times has the answer: death (not the band, of course).
